DESCRIPTIONThe PDSP16350 provides an integrated solution to the need for very accurate, digitised, sine and cosine waveforms. Both these waveforms are produced simultaneously, with 16 bit amplitude accuracy, and are synthesised using a 34 bit phase accumulator. The more significant bits of this provide 16 bits of phase accuracy for the sine and cosine look up tables.With a 20 MHz system clock, waveforms up to 10 MHz can be produced, with 0.001 Hz resolution. If frequency modulation is required with no discontinuities, the phase increment value can be changed linearly on every clock cycle. Alternatively absolute phase jumps can be made to any phase value.The provision of two output multipliers allows the sine and cosine waveforms to be amplitude modulated with a 16 bit value present on the input port. This option can also be used to generate the in-phase and quadrature components from an incoming signal. This I/Q split function is required by systems which employ complex signal processing.

DescriptionThe ZL30402 is a Network Element Phase-Locked Loop designed to synchronize SDH and SONET systems. In addition, it generates multiple clocks for legacy PDH equipment and provides timing for ST-BUS and GCI backplanes.The ZL30402 operates in NORMAL (LOCKED), HOLDOVER and FREE-RUN modes to ensure that in the presence of jitter, wander and interruptions to the reference signals, the generated clocks meet international standards. The filtering characteristics of the PLL are hardware or software selectable and they do not require any external adjustable components. The ZL30402 uses an external 20 MHz Master Clock Oscillator to provide a stable timing source for the HOLDOVER operation.The ZL30402 operates from a single 3.3 V power supply and offers a 5 V tolerant microprocessor interface.

DescriptionThe ZL60214 video IP surveillance camera cable extender module is a fully integrated device designed for direct connection between two types of media, 10/100Base-TX (Fast Ethernet on shielded/unshielded twisted pair copper cables (STP/UTP) and 100Base-FX (Fast Ethernet on multi-mode fiber) with single fiber, to extend the network reach up to 2 km.The Link is based on Zarlink’s world class family of high-performance LEDs, VCSELs and PINs and have been optimized to offer excellent optical coupling efficiency in combination with high bandwidth operation and extremely good reliability.The optical part of the modules uses dichronic beamsplitters for maximum optical power budget and minimum crosstalk. Minimum internal crosstalk is achieved by the use of wavelength-selective detectors.The Modules is designed for multi-mode fiber and optimized for 62.5/125 μm fiber.The link offers attractive advantages in terms of weight and flexibility that allows the device to be attached directly to the copper cable and fit inside the outdoor protective housing for the IP camera.Power supply of 100 to 230 V AC.The part is compliant to the EU directive 2002/95/EC issued 27 January 2003 [RoHS] with exception number 6.

DescriptionThe MT9171 (DSIC) and MT9172 (DNIC) are pin for pin compatible replacements for the MT8971 and MT8972, respectively. They are multi-function devices capable of providing high speed, full duplex digital transmission up to 160 kbit/s over a twisted wire pair.They use adaptive echo-cancelling techniques and transfer data in (2B+D) format compatible to the ISDN basic rate. Several modes of operation allow an easy interface to digital telecommunication networks including use as a high speed limited distance modem with data rates up to 160 kbit/s. Both devices function identically but with the DSIC having a shorter maximum loop reach specification. The generic "DNIC" will be used to reference both devices unless otherwise noted. The MT9171/72 is fabricated in Zarlink’s ISO2-CMOS process.
